Issue with GTM/LTM SNMP udp_gtm_dns
Hi, Im having the following problem with 4 big ip 1600 (currently running GTM) This 4 boxes are working as two separate clusters active/standby. I have a cacti learning with snmp the amount of total connections and it tells me that i have 8 millions in GTM-A-1 and in the other cluster GTM-B-1 (hipotetical names) i have 10 thousands of conections, always talking about the active server. The standby servers also give me via snmp info related to conections (like 3 or 4 alone connections, i assumed this was a bug)
Important fact: When i enter the dashboard of the GTMs they tell me something very diferent like no Open Conections, zero. I dont have this issue with another cluster of BigIP 2000s (Newer Version, same service and isolated from these other 2 clusters that are giving me a headache.) for the same service.
All of this as UDP Open conections - udp_gtm_dns on my cacti.
(They are resolving querys for mobility in 3G, Gn interface)
Then, to sumarize: I have two clusters and one of them have 8 million connections while the other doesn't have any related to that one. They are in the same GTM Group (replicating zones)
The partner that sold the appliances told me that i should boot over the two clusters but im searching for a different approach. Maybe something is slipping from me in cacti in method of how it graphics
That with the GTMs.
Now, with LTMs (Big IP 4200v) i have a similar issue. I have 2 Clusters balancing DNS querys to two different DNS servers. By datasheet, each appliance have a maximum 2.5 million L4 http Request per second, and 10 million maximum concurrent conections. Past month, with cacti i had 88k QuerysPerSecond (in my DNS servers) and 3.9millions conections in the LTM (using the same object as with the GTMs: UDP Open Conections udp_gtm_dns) This month, i have 135 kqps (growing fast) and 4.1million conections. There is something that im definitely doing wrong here or all my different appliances from f5 have issues with udp "conections".
Did somebody had the same issue? Thanks in advance! Joel.
